GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 226,785, dated April20, 1880.

Application filed December 26, 1879.

To all whom it may concern Be it known that I, HENRY E. PRIDMORE, ofBrockport, in the county of Monroe and State of New York, have inventeda new and useful Improvement in Grain-Binders, which improvement isfully set forth in the following specification and accoi'npanyingdrawings, in which- Figure 1 is a general plan of a portion of a reaperat the inner end of the sickle-bar, showing the relation between thebinding mechanism and other parts of the reaper; Fig. 2, an enlargedplan of the binding mechanism, showing the same more fully than Fig. 1;Fig. 3,

Figs. 11 to 14, inclusive,

show the positions of the knotter at every onefourth rotation of thesame made in developing the knot in the twine; and. Figs. 15 and 16,Sheet 1, and Fig. 17, Sheet 2, details.

My invention relates to automatic twinebinding attachments tograin-harvesters; and it consists, mainly, in new and novelconstruetions of the twine-holding device and twinecutter and of thetwine-tying device or knot- 0 ter, and of the manner of operating thesaid devices, allhereinafter fully described.

Referring to the drawings, the various arrows A indicate the directionof the advance of the reaper. p

In Fig.1, B is the sickle-bar, G the platform, and D the foot of therake-standard, of an ordinary grain-harvester. Eis a secondary platform,upon which the binding is done, being an extension to the main platform0, but depressed below the level of the same.

F, iii-dotted lines, is a frame carrying the binding device 5 and J, thebinder-arm, secured at the end of a horizontal shaft, K, resting in orupon the platform E.

Figs. 2, 3, and at, Sheet 2, show the frame F, with its attachments,more fully drawn and to a larger scale.

L, L, and L are three sinuous slots or grooves formed in the platform E,mainly concentric with the vertical stud Gr, constituting cam ersextending into the same from beneath the frame F. I

To operate the several parts of the binder and effect the binding of thesheaf the frame F is caused to swing horizontally around the fixedpivotal stud Gr through an arc of ninety degrees. (See Fig. 4.) Theirregularities of the grooves L, L, and L followed by the respectiverollers, cause the parts to operate in manners hereinafter described.

I is a crank-arm, secured to the frame F by means of a sleeve journaledupon the stud Gr, rising from the platform E, and the said frame iscaused to swing to and fro, as above described, by means of aconnecting-rod, H, attached to said crank-arm, and at the other end tosome suitable crank 0r rocker arm of the machine capable of giving thesaid rod reciprocal l1l0- tion.

Figs. 1, 2, and3 show the parts of the binder and the frame F in theirnormal positions and at rest, waiting the gathering of a gavel to bebound.

The cut grain upon the platform at G is carried by the ordinaryharvester-rakes around upon the platform. E, as shown in dotted lines,over the binding-twine b. after which the carried over the grain to'thetwine-clampin g jaws by means of a connecting-rod attached to thecrank-arm M or other suitable means, when the frame F, with thetwine-encircled 'avel is swun around as above described ways or tracksfor three studs or vertical rollpoint of the binder-arm J, with thetwine, is

during which the sheaf is bound and deliverd upon the ground, asindicated in dotted lines in Fig. 4.

Referring to the manner of holding and cutting the twine, d, Figs. 2 and16, is a fixed vertical stud secured in the frame F, upon which isjournaled a sleeve,f, carrying two horizontal arms, N and g. The lowerarm, g, has a vertical stud, h, provided with a frictionroller, whichextends down into the slot L of the platform E, above described. Theupper arm, N, carries the twine clamping and cutting devices. A secondsleeve, 0, isjournaled upon the sleeve f, which is provided with ahorizontal plate, P, and arm, 70, which latter has a stud, l, reachingdown into the slot L in the platform E.

t will be understood that were the frame F swung as above described,bringing the stud h to a crook in the slot L, carrying it nearer to thepivotal point Gr, the arms hand 'N, Fi 2, would be swung as indicated bythe arrows, and vice versa; and if the stud l he brought to a crook inthe slot L, carrying it farther from said point G, the arm is and plateP would be carried in the direction indicated by their respectivearrows, and vice versa.

Fig.5, Sheet 1, and Figs. 6 and 7, Sheet 2, are views ofthearni N, withits attachments, drawn to a larger scale. The arm N has a finger, 1),extending upward from beyond its end, curvin goutward at the top, and areversely-curved finger, t, being the upturned end of a spring, I),lying upon and pivoted to the arm N, said fingers forming clamping-jaws,between which the band-twine is held. The spring finger or jaw t laps bythe jaw 17, as shown in Fig. 7, and when the twine I) is forced betweenthem it springs thejaw tback, and is held by virtue of the stiffness ofthe spring I).

Q is a driving-head, pivoted at m betwcen two upturned flanges of thearm N, and connected by a rod, It, to a stud, w, fixed in the plate P.When the head Q, is caused to descend it drives the twine betweenthejaws, as shown. The descent of the head is caused by the plate P,Figs. 5 and 6, being turned in the direction indicated by the respectivearrows by means of the roller Z, Fig. 2, passing the crook t in the slotL, as above described.

When the parts are at rest, as shown in Fig. 2, waiting to receive agavel, the head Q is raised, and the binder'arm J, when a gavel iscollected, brings the twine across between the retainin g-jaws tp, asindicated by the dotted line b. The movements of the parts are so timedthat the frame F commences to swing the instant the twine is thuspresented to the jaws, and the roller Z, quickly reaching the crook 45,brings the head down and drives the single twine (the other end of thesame being already retained there from the last operation of binding agavel) between the jaws, as above described; but soon after the roller 1passes the said crook the roller h arrives at a reversed crook, j, inthe slot L, Fig. 4:, which swings the arm N back toward the vertical webB, and this motion, as it increases the distance between the head Q andpin w, again raises the head.

d, Figs. '5 and 7, is acutter for severing the twine at the right momentagainst the side of the jaw 19, which forms a part of the shear. Saidcutter is connected by a rod, S, with a stud,f, of the plate P, and iscaused to slide endwise within its guides longitudinally by the side ofthe arm N by means of the rollers l and h passing the crooks in theirrespective slots, above described. In its normal position the cutter isdrawn considerably back from the jaw 19,- but as the arm N is swung tothe position shown in Fig. 4 its cutting endis presented close to thetwine, as shown in Fig. 7, and when the roller 1 arrives at the crook gin the slot L the twine, by a sudden movement of the cutter, is severed.

T, Figs. 2 and 3, is a twine-gathering device, the duty of which is tobring the upper strand of the band, after the same has been broughtaround the gavel, down close to and parallel with the lower strand,preparatory to being tied by the knotter. Fig. 15 shows in outline thetwine before and after the upper inclined strand has been gathered tothe lower one by the action of the gatherer T. The gatherer is hung upona horizontal pin, a, projecting from a crank-arm, h, secured to apinion, U, journaled upon a stud projecting from the vertical plate B ofthe frame F. The pinion is given at intervals a quarter-rotation bymeans of a segment of gear, 0, which is oscillated by a connecting-rod,c, joined to the arm k, said motion being given to the segment when theroller 1 passes the crook i of the slot L. The two positions of theparts are shown by the full and dotted line positions in Fig. 3.

The clamping-jaws t and 19, Figs. 2 and 3, the orifice 8 through thevertical plate B, and the point of the binder-arm in its normalposition, as shown in Fig. l, are in a straight line and on a level, sothat the twine, held at the end in the said jaws, and also by the pointof the arm, lies horizontally through the said orifice but when broughtaround the gave] and again to the jaws the' upper strand passes throughthe slit 0 of the plate B at a point about at 0, slightly below theextreme end of the gatherer, and is carried down to the orifice s by thedescent of the gatherer, as above described. There are pins '0 1;, oneabove and one below the gatherer, which form guides for the same, theone above causing the gatherer to move forward nearly horizontally overthe twine for a short distance before it descends.

Y, Figs. 2 and 3, is a gavel-receiver, (shown in dotted lines in Fig.1,) which receives the gavels as they are brought to the binder, andwhich also shields the twine b from the grain as the same is broughtover it by the rakes. Its left-hand edge, as appearing in said figures,is on a level with the platform 0, while the opposite edge is raised tothe orifice s of the plate B, or a little above the twine as it liesready to receive the gavel. By means of this gavel-receiver or chute thegavel, when presented to the binder, is carried over the twine. Thegavel-receiver is secured to the plate B of the frame F, and swings withit.

V is a segment of gear pivoted upon a vertical stud, n, fastened to theframe F, and is provided with a stud and roller, a, extending down intotheslot L of the platform E. The slot L is so shaped that when the frameF is swung around, the stud a, following said slot, causes the segment Vto turn upon its pivot to the position shown in Fig. 4, there being acircular slot, a cut through the frame to make way for the stud.

X is a pinion, whose teeth engage those of the segment V, which, withits sleeve, is journaled in a bracket or support, y rising from theframe F, within which sleeve and pinion rests a horizontal spindle, A,which constitutes the body of the twine-knotter. The spindle A, fittingwithin the sleeve, has an ordinary slot and feather or spline, whichallows it to slide longitudinally through the sleeve; but both mustrotate together.

A curved link, 1), reaches from the crankarm I to a point near to andbeneath the knotter-spindle, to which it is connected by means ofanother short link, 8, secured to a looselyfitting collar, 1?, Fig. 9,Sheet 2, upon said spindle.

k is a slotted bar connected with the bolt 0 that joins the links 1) ands, which receives in its slot the upper end of a vertical stud, I,secured to some suitable part of the reaperframe.

When the frame F is swung well around the extreme end of the slot willarrive at the stud l and check or stop the motion of the bar k, and ifthe motion of the frame be continued the spindle A will, in consequenceof the said stopping of the bar It, be drawn back endwise partiallythrough the pinion, the positions of these several parts when the frameis swung fully around being shown in dotted lines in Fig. 4.

When the frame F is brought back to the position shown in Fig. 2 theopposite end of the slot will be brought against the stud l and causethe spindle A to slide through the pinion to its normal position. Theuse of these endwise motions of the knotter-spindle or parts of the samewill presently be understood.

Figs. 8 to 14, inclusive, Sheet 2, show the knotter and the manner oftying the knot.

D, Figs. 8, 9, and 10, is a sleeve forming one piece with the pinion X,Fig. 2, journaled in the bracket 3 within which sleeve is secured agrooved stockpiece, F, which holds the twineknotter proper. The saidstock F has two broad unequally-deep rectangular longitudinal groovescut in its opposite sides, and approaching each other so that but a thinweb, 6, of the stock separates them.

Within the shallower groove, near the nose of the stock, is pivoted at ra hook, at. A bifurcated sliding piece, G, rests within the grooves ofthe stock F, the branches 'i and u of which straddle the web 6, asshown, the shorter and thicker branch u occupying the groove containingthe hook n. The hook it has at its reverse end a short slightly-bentshank, 0, and the inner side of the branch a, near its end, is cut away,leaving a knob, to, (see Fig. 17,) which, as the sliding piece G of theknotterspindle is moved backward or forward by means of the slotted barIt and stud 1, above described, acts upon said shank to operate the hook02. As shown in Fig. 9, the knob 20, in its forward movement, has passedthe shank 0, and, pressing upon the body of the hook beyond the pivot r,forces it to assume the position shown in full lines. The beveled part cof the branch u, pressing beneath the end of the shank, also assists tohold the hook in the position shown.

If the slide G be partially withdrawn the knob u will press upon theupturned portion of the shank and move the hook to the position shown indotted lines.

The thinner branch i of the slide G extends through and beyond the noseof the stock, and has a rectangular notch, 00, Figs. 9 and 17, cut inone edge near the end, forming a straight hook, 2, which is drawn withinthe stock F when the slide G is drawn back, as above explained, thesemotions of the hooks n and 2 being essential to the tying of the knot.

1", Fig. 10, is a spring secured within the sleeve. D, and lying in aslot of the stock' F by the side of the branch t" of the slide G, whichserves as a tension for the end of the twine as the knot is being drawntight.

Fig. 9 shows the partsin position when ready to act upon the twine toform the knot. The heavy dotted line b represents'the relative positionof the band as it is presented to the knotter by the binder-arm andgatherer T, above described, the gavel bein g at H and clampingjawsat 1. It requires pne and one-fourth rotation of the knotter to completethe knot, the direction of rotation being indicated by the arrow as.

Fig. 10 shows the knotter after having rotated one-fourth around, thehook n having caught the twines of the band. Figs. 11, 12, and 13 showthe positions at the successive quarter-rotation of the knotter, andFig. 14 when one and one-fourth rotation are made, the loop of the twinehaving been completed, (one strand of the band only being shown in thesefigures.)

At this stage of the opera-tion the strands of the band are severed bythe cutter d, Fig. 7, above described, and the slide G is drawn backwithin the stock F by means of the slotted bar It, above explained. Bythe drawing back of the slide the hook 2 draws the ends I of the twine,which now lie across within the notch w, as shown in Fig. 14, throughtheloop, the hook n being simultaneously withdrawn IIS from the loop bybeing thrown back,as shown in the dotted position in Fig. 9, effected bymeans of the knob u, as above described. After the withdrawal of thehook at the loop is per- 5 mitted to slip off the nose of the stock, the

knot being completed at the end thereof, said loop being assisted offthe stock by means of a short quick crook, p Figs. 1 and 4, in the slotL,which suddenly throws the twine-clam ps 1o 19 tin a direction towardthe plate B for the purpose.

0, Figs. 2 and 3, is a bent offset plate attached to the plate B, havinga hole, 8, opposite the hole 8 in said plate, within which the book 2 ofthe knotter turns as the stock A is being rotated to form the loop ofthe knot. The end or point of the hook 2 moves around close to theperiphery of the hole, as shown in Figs. 11 and 13, which insures thetwine I) leading from the gavel being kept on the proper side of thehook, so as to be crossed by the twine leading from the clamping-jaws,thus completing the loop, as shown in Fig. 14. This guard-plate O has aflaring opening, as shown, leading upward from the orifice s to receivethe twine brought down by the gatherer T, as above stated. 1

Fig. 17 shows the ends of the (wine after having been severed by thecutter near the clamps as being drawn within the stock by the hook z.The spring r pressing against the said twine gives the hook z asuffieient hold upon the twine by which to draw the knot tight.

The knotter operates close to the side of the bundle, and draws upon thehand during the formation of the loop, so that the band may be madesufficiently tight upon the bundle. The motion of the arm N, carryingthe twineclamps toward the knotter, as above described, is designed tobe so regulated asto yield twine to the latter no faster than it isrequired to form the loop, so that said knotter shall keep a steady andunbroken draft upon the band of the sheaf to insure sufficient tensionof said band.

By observing Figs. 1 and 2 it will be seen that the segment V does notcommence to turn upon its pivot at once when the frame F is startedaround by the rod H, for the slot L is widened at a, so that the stud a.of the segment, for some little ti me after the frame has started, movesthrough space without elfectin g anything; also, that the arm N remainsat rest for some little time after the frame starts that is, until thestud it arrives at the erookj in the slot L, but that the arm 70commences to swing upon its pivot (I immediately upon the starting ofthe frame, for the crook i of the slot L being at hand, the roller Zcommences to traverse it at once.

Now, the swinging of the arm 70, as above set forth, effects two thingssimultaneously: It throws the driving-head Q down and drives the twinein between the clampingg'aws to secure it, and carries the gatherer Tdown, bringing the two strands of the band together across theknotter-hooks. During the time in which these things are being effectedthe stud a will cross the wide part of the slot L and come in contactwith the opposite side and start the knotter, and the stud It will reachthe crook j at the same instant and commence to swing the arm N, withthe clamps, toward the knotter to supply twine for the loop.
